[rancid] output that triggers annoying email notification - I am sure we have all seen this before from rancid. :)

I haven't heard back so I went ahead and comment out the line below:

{'show system' => 'ShowChassis'},

Unfortunately, it removed a lot of valuable information so I am going to
attempt to 'intercept' the output files and remove the '!Chassis...' line
there in the file:

- !Chassis: 0 up medium up up up up up
up
+ !Chassis: 0 up low up up up up up
up

I think I narrow down it to the following in the bin/f10rancid:

...
...
...
open(OUTPUT,">$host.new") || die "Can't open $host.new for writing: $!\n";
select(OUTPUT);
# make OUTPUT unbuffered if debugging
if ($debug) { $| = 1; }

if ($file) {
print STDERR "opening file $host\n" if ($debug);
print STDOUT "opening file $host\n" if ($log);
open(INPUT,"<$host") || die "open failed for $host: $!\n";
} else {
print STDERR "executing clogin -t $timeo -c\"$cisco_cmds\" $host\n" if
($debug);
print STDOUT "executing clogin -t $timeo -c\"$cisco_cmds\" $host\n" if
($log);
if (defined($ENV{NOPIPE})) {
system "clogin -t $timeo -c \"$cisco_cmds\" $host </dev/null > $host.raw
2>&1" || die "clogin failed for $host: $!\n";
open(INPUT, "< $host.raw") || die "clogin failed for $host: $!\n";
} else {
open(INPUT,"clogin -t $timeo -c \"$cisco_cmds\" $host </dev/null |") ||
die "clogin failed for $host: $!\n";
}
}
...
...
...

Do let me know if I am completely off base here.

All,
I am using rancid 2.3.2. with force 10 switches (S50N - 48-port).
The following line keeps triggering an email notification, which is
annoying because we get desensitized to the notification email when there is
an actual change.
- !Chassis: 0 up medium up up up up up
up
+ !Chassis: 0 up low up up up up up
up
The router command that spit out this status is (I believe) 'show system'.
bin/f10rancid: {'show system' => 'ShowChassis'},
I am going to hack the script to see if I can filter the annoying output.
I will probably will remove the command 'show system' if I don't figure out
how to filter out the annoying line. But this affect the output globally
and I would like to get the rest of the output.
I was wondering if someone has experience changing the code base to deal w/
this case? Any pointer would be apreciated. Thanks!
